2 Claims.

My invention pertains to a lock handle for the outside manual and key control of door locks which may be latchedirom the inside, and to a method of assembly.

-' iIt isan object of my invention to provide an improved handle for the combined direct man-' ual or key'control of a door lock from the outside, even when it has been latched from the inside, and to an improved method of ,assembly therefor. I

It is also an object of my invention to provide such a door lock handle assembly which will be a simple rugged construction, convenient to assemble and durable in operation.

, It is a further object of my invention to provide an improved door lock handle for the combined direct manual and key control from the outside of a door lock having a larger radius for the key controlled or releasing mechanism.v

The invention itself, howevenbothas to its construction and its use, together with additional ing a dog or latch, in response to the insertion of a proper key byan authorized person.

As shown in Figs. 2, 3 and 4, the hub extension l3 may'preferably be a tubular member shapedat the extended end to the desired non-circular cross-section l5 and having the handle H die cast with a hub l6 on the other end, or these may be formed integral if desired. The split cam sleeve I1 is of a substantially cylindrical conformation adapted to fit loosely upon the extension, and the cam I9 is a lug projecting from one side thereof.

ferentially in the side wall of the cam sleeve, is

A slot 2|, elongated .circumdisposed substantially in alignment with a'slot 23 in the side wall of the tubular extension. Slot 2| extends a substantially lesser distance circumferentially in the cam sleeve than does the objects and advantages thereof, will best be understood from the following description of spe-' cific embodiments, when read in conjunction with the accompanying drawing, in which:

Fig. l is a side elevational view showing an assembled handle for the outside manual or key control of a door lock in accordance with my invention; v

Fig. 2 is a longitudinal sectional view taken axially through the handle assembly;

Fig. 3 is an enlarged cross-sectional view taken on line 3-3 of Fig. .1; I v I Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 1; and

Fig. 5 is a diagrammatic view illustrating operative relation of the relatively movable parts of the handle.

Referring more specifically to Fig. 1, I have illustratively disclosed my improved door lock handle for combined outside manualand key control, comprising a handle ll having an elongated hub and extension l3 projecting from one side and suitably conformed at the end l5 as by being non-circular or square .in cross-section, for operative engagement into a similarly shaped aperture in any lock member, such as a rollback, to be actuated from the handle, as. will be slot 23 in the extension. A look barrel 25 is rotatively disposed in the aperture in the handle in a bushing 21 which is provided'with two tumbler recesses 29, adapted to receive the tumblers 3|. The bushing 21 is connected, by interconnecting parts 33, with the tubular extension member.

operatively connected to the lock barrel, as by dieoasting. together, is a spindle 35 which extends in the aperture'in the tubular extension and has a hole 31 disposed at a suitable axial position so that when fully inserted it is in alignment with the slot 23 in the tubular extension. When the hole 31 and the two slots 2| and 23 are brought into axial alignment, a knurled pin 39 is inserted through these slots and is pushed snugly into the hole in the spindle to prevent relative longitudinal displacement of the spindle, the tubular extension, and the cam sleeve. A certain amount of relative angular rotation is provided, as determined by the circumferential lengths of these adjacent slots, so that sumciently turning the lock spindle. 35 by a key 41 may turn the cam sleeve I! on the tubular extension, while the latter remains stationary. The cam sleeve I! has at all times a certain amount of free rotary or angular movement on the tubular member l3.

The lock handle assembly is rotatively installed in a vehicle door, in a usual manner, with the handle ll being exposed on the outside, and the operative end l5 and cam l9 being operatively engaged with parts of the lock to be controlled by the handle H and the lock 25 respectively.

gle, in a manner to be described, for performing some other operation in a lock, such as'releas- The relation of the installed handle to parts of the lock to'b'e controlled, shown dotted, is represented diagrammatically in Fig. 5. The element shown clotted, and designated 43, represents any part of a lock, such as a rollback to be rotated from the inner end l5 by turning the outside handle. The dotted element 45 represents a lock part, such as a latching dog, engaged with the cam 19 to be controlled from the outside by means of a key M. As will be understood, the elements 43 and 45 may be any parts to be moved or actuated.

It is apparent that within the scope of my invention modifications and different arrangements may beLmade-other than herein disclosed, and the present disclosure is illustrative merely, the invention comprehending variations thereof,

I claim:

1. The combination in a door lock handle for the outside manual and key control of a door.

upon the hub extension, a camming projection on said sleeve, a circumferentially extending slot in said cam sleeve, a pin in the transverse hole in the spindle and projecting through the slot in the hub extension for holding the spindle from longitudinal movement and projecting still further into the slot in the cam sleeve for hOlding the sleeve from longitudinal movement and for rotating the sleeve for accomplishing a control operations 2L Acombination manual andkey control for door locks comprising, three relatively movable concentrically disposed members, the intermediate one of said members having one end conformed for operativ coupling with a device to be controlled and its other end being adapted for convenient manipulation, the outermost of said concentrically disposed members being conformed for operative engagement with a device to be controlled, slack motion coupling means for transmitting operative movement from one end of the centralmember to the outermost concentric member while' permitting the latter'to have a limited amount of free'an-gular'movement, a lock barreldis'posed in alignment with the other end I'of .thezcentral member, and saidiother end of said centrally disposed member being connected with" said lock."v barrel forfoperation by a person having a suitableikey;
